I plan on playing FE11 with reclassed units, and one of those I want to (hopefully) be a Cavalier Marth. I attempted to open up the game in Nightmare but all the files are wacky, so if someone could do that, that would be great. If Falchion and village visiting has to be applicable to all cavaliers/paladins that’s cool too.
Did you use DSlazy(or something similar) to unpack the ROM first? Then after that, I believe you use nintenlord’s compressor to decompress the files to be usable in Nightmare/hex editing.
